Rifle safety for low caliber .22 cartridges and similar calibers

ABSTRACT

This invention refers to a new safety, incorporated toward the end of the mechanism chamber of a double-shot rifle, located slightly behind the trigger, whose safety has a movement toward the back which occurs automatically upon moving the bolt handle to remove the shell or the cartridge and prepare the rifle, leaving the safety in place for its shot, and where the safety is removed manually upon moving the safety toward the front of the gun when the arm is ready for shooting. The safety is formed by a trigger safety to prevent accidental firing of the weapon and is fit to the combination of a rectangular plate in whose base there is a mechanism release window corresponding to the track of the trigger having in addition some bores in its corners in eyelet form that serve as guides for the course and movement of the trigger safety.

FIELD OF THE INVENTION

This invention is used as an article for sports and diversion,particularly for young adult males. In this case, the invention'sobjectives contribute to preventing all types of chance accidentsresulting from improper use of the gun, whether it be accidental due tounfamiliarity with the gun or whether it be due to the inappropriate useof the gun.

Due to the above, this invention has as its objective the realm ofcartridge rifles. Upon activation of the invention, the gun is left in asecure condition; in addition, the invention allows the gun to bechanged from a double-shot to a repetition rifle.

BACKGROUND OF THE INVENTION

As it is widely known, there are many types of safeties for weaponswhich have been discussed in various patents, citing for example U.S.Pat. Nos. 1,164,646; 1,509,257; 2,729,28; 3,465,741; and 3,839,999;referring briefly to the following considerations.

1. U.S. Pat. No. 1,164,646 (Pop Rifle—Heyman and Arden) dated Dec. 21,1915, publishes a shooting mechanism for a children's sporting corkrifle.

The mechanism being proposed differs from that patent because in theabove-mentioned patent, when the cam is lowered to get ready to shoot,the gun is not locked. The proposed invention includes a latch that isautomatically locked when the gun is loaded and which must be releasedmanually.

2. U.S. Pat. No. 1,509,257 (Air Gun or Rifle—Randall) dated Feb. 26,1926, lays claim to a spring mechanism for air rifles.

Although said invention preceded this proposal, it does not include asafety mechanism to prevent accidental shooting nor does it prevent ashot when the cam is not in place, in which case the user's fingers maybe smashed by the cam when the gun is shot.

3. U.S. Pat. No. 2,729,208 (Popgun—Gaeke) dated Sep. 11, 1953, protectsan air rifle from going off. Its mechanism produces a sound similar tothat of a real rifle. Additionally, the cam blocks the shootingmechanism but not the trigger directly.

4. U.S. Pat. No. 2,837,865 (Popgun construction—Wells) dated Jun. 10,1958, publishes a mechanism consisting of a valve through which a blastfor toy popguns with corks is produced.

5. U.S. Pat. No. 3,465,741 (Popgun with extended barrel for protectingpuff of air—Daniel, et al) dated Jun. 15, 1965, refers to a mechanismthat produces a blast for a popgun by means of a valve. Therefore, thisinvention differs appreciably from the proposal. Even though there mightbe elements that are the same or similar, the arrangement of such istotally different.

6. U.S. Pat. No. 3,839,999 (Gun with Safety Member MountedTherein—Fleming) refers to a lateral safety activated by several tensioncams. The invention proposed is different due to the fact that it refersto a button which operates directly without a cam mechanism.

Apart from the last invention, which has an auxiliary safety, the othersdo not present any type of safety for the protection of the rifle whenit is loaded.

It has been observed that in some cases, a lack of knowledge of themechanism of the gun has caused some minor injuries to the users,particularly to their fingers and hands. This is due to excessiveconfidence and to the curiosity to investigate the results of having therifle in an other-than-normal position.

Referring specifically to the cartridge rifle with a reloading lever,the safety is put in place, clasping a part below the trigger; it isremoved after the rifle is loaded and ready to shoot.

It may be said that in agreement with the antecedents and to the bestknowledge of the patent-seeker, no other invention close to the proposedone is known. Therefore, the improvements made constitute a newinvention.

BRIEF SUMMARY OF THE INVENTION

The purpose of this invention is to prevent accidents by the user at themoment of involuntary movement of the safety when the gun is preparedfor shooting.

Another goal of this invention is to have the safety external to thesport cartridge rifle equipped with safety mechanisms and to avoid theinvoluntary removal of the safety therefore minimizing any chanceaccidents due to inadequate handling or lack of knowledge of the same.

Another objective of this invention is that of an external safety whichcomplies satisfactorily with safety regulations and security norms.

Another purpose of this invention is to prevent the removal of thesafety if or when the rifle falls to the ground and hits exactly on thesafety.

This invention refers to a new safety, incorporated toward the end ofthe mechanism chamber of a double-shot rifle, located slightly behindthe trigger, whose safety has a movement toward the back which occursautomatically upon moving the bolt handle to remove the shell or thecartridge and prepare the rifle, leaving said safety in place for itsshot, and where said safety is removed manually upon moving said safetytoward the front of the gun when it is ready for shooting.

Said safety has a spring that upon moving the safety, produces anaudible click by which one has the certainty that the safety is in oneposition or the other. In addition there is a red point on the butt fornoting that the bore of the safety is properly aligned with the butt.

Also, said safety consists of two screws which act in the front as acatch for the retrogression handle in such a way that when removing thefirst screw in the front, a double-shot rifle can be converted into acommon repetition rifle.

The development of different types of safeties for guns has beendiscussed in various patents including U.S. Pat. Nos. 1,164,646;1,509,257; 2,729,28; 3,465,741; and 3,839,999.

DETAILED DESCRIPTION OF THE INVENTION

This invention refers to a safety for cartridge rifles by which safeoperation of the rifle is guaranteed, preventing an accident due toinappropriate use by minors or adults.

With reference to the cited figures, the rifle with said safety consistsof a combination of a barrel 70 at the front through which the bullet orpellet will be shot, followed by a mechanism chamber 72 where the firingmechanism is located, and by the butt 74, which serves as a support forthe barrel 70 and the mechanism chamber 72 when firing.

Toward the end of the mechanism chamber 72, present on the upperleft-hand side, is a cartridge feeder 20 where a cartridge that isinserted will be fed automatically. Also located there is a secondcartridge which stays in the rifle chamber in such a way that the riflecan be converted to a double-shot type or the repetition type and wherethe cartridge feeder 20, formed by a curved plate conforming to thecylindrical curvature of the cartridge casing, is a spring that stopsthe second cartridge so that it does not come out of place and where thebullet or pellet is fed into the chamber of the rifle upon the openingof a bolt 30 whose function is that of introducing a cartridge into theinterior of the chamber for its later detonation and at the same time ofextracting the casing once it has been detonated.

This bolt 30 consists of a cylindrical piece which has at the end astriker 32, whose function is to detonate the cartridge, formed by araised edge on its cylindrical face, and an extractor 34 with thefunction of extracting the shell of the detonated bullet or thecartridge at the moment said bolt 30 is moved. Toward the opposite end,there is a bolt handle 36, consisting of a cam, attached so that it isperpendicular to the cylindrical piece and fixed to the cylinder, whosefunction will be to move the bolt 30 in a rocking motion toward thefront and the back, having in addition a small groove above the straightpart of the cylinder forming the step of the release 38 that aligns witha groove on the trigger 51 and a V-cut 41 at the end of the cylindricalpart, which should align with a hammer 40, whose function is to hit theperforator that is inside the bolt 30 and this, in turn, impact thecartridge.

This hammer 40 is a hollow cylindrical piece forming a ring with wallsat one end and having a V-shaped protuberance 43 which aligns with theV-shaped cut on the bolt 30 by which exact alignment of the hammer 40with the bolt 30 is assured and toward which the straight part of thecylinder presents a catch 42, whose function will be to prevent thecylinder from turning, consisting of a small round-headed pin, connectedtransversely, and where at the interior of the cylinder is located ascrew 44 and which unites with an alignment thread located in the centerof the bolt 30 in such a way that the pieces are joined, in addition,there is a screw 46 inside the cylinder that fixes the interior walls ofthe end, in such a way that the screw 44 keeps the two parts in a fixedposition and at the same time permits both pieces to run to one side.

Under the hammer assembly 40 appears the trigger 50, whose function isto cause the execution of the impact of the cartridge. Connected to aplate, it is the piece below in the form of a canal with an elongated,slightly curved portion where the finger is rested to shoot the weapon.This is mounted on the trigger support 52, made up of a rectangularplate to which is attached the end of the trigger 50. Extending past thetrigger 52, there is a protuberance which fits into the end of thetrigger 50 with which the cut of the trigger 51 is formed and where saidprotuberance halts the advance of the hammer 40 when the rifle is loadedand at the same time leaves the hammer 40 free at the time of firing. Inaddition, the trigger support 52 has at its other end a bore for thepassing and fixing of the trigger support 52 by way of a screw 54 andwhere there is also a spring 56 which stays compressed as much becauseof said screw 54 as because of the trigger support 52 upon its fasteningin the mechanism chamber 72 in such a way that, upon pulling the trigger50, the trigger support 52, with the screw 54 and the spring 56, moveabout a fixed point that corresponds to the point at which the screwassembly and the spring join.

The trigger safety 60 functions so as to prevent accidental firing ofthe weapon and is fit to the combination of a rectangular plate in whosebase there is a mechanism release window 62 corresponding to the trackof the trigger 50 having in addition some bores 64 in its corners ineyelet form that serve as guides for the course and movement of thetrigger safety 60. From the base of the rectangular plate, the platecontinues with a section at ninety degrees and some curved piecesfollowing the contour of the mechanism chamber 72, ending with ahorizontal segment at each side; said safety is attached in its curvedsections via conventional screws and where on the right-hand side of thecurved extension is a spring 66 by which is determined the movement ofsafety release, signaled with a click, consisting of a flat plate inwhose center there is a vertical mark and that aligns with the alignmentgrooves located on the surface of the curved part of the safety 60. Onthe other side, the right-hand extension has on its face two threadedbores where two return stop screws 68 and 69 are fixed. The first actsas a return stop where upon moving the bolt handle 36 to load the rifle,the return stop screw 68 moves and brings the safety 69 toward the backin a secure position and at the same time brings the hammer 40 to itsfinal position and brings the protuberance into alignment with theterminal of the trigger 50 in front of the hammer 40 at which point itwill be in position for loading Meanwhile the second return stop willact as a point or peg to activate and release the safety 60 manually.

In addition, it has a third bore 63 that serves as a window forobserving the red alert point 75 marked on the butt.

BEST WAY TO OPERATE THE INVENTION

Operating the above-described mechanism is extremely simple.

The rifle is opened via the bolt handle 36, which pushes the hammer 40and the trigger safety 60 into the loaded position A cartridge is fixedin the rifle chamber.

The action of loading is completed at the moment at which the bolthandle 36 pushes the cartridge into the chamber, where the hammer 40 isstopped by the action of the protuberance corresponding to the terminalof the trigger 50, and although a shot may be attempted, the rifle willbe in a secure state. A second cartridge may be introduced into thecartridge feeder 20.

Firing the rifle is achieved by manually releasing the trigger safety60, lightly pushing toward the front, in which case a click will beheard when the vertical marking of the spring 66 aligns with thevertical alignment grooves is the curved piece. The red alert point maybe observed through the security window or bore 63. At this time, thetrigger 50 is pulled, leaving the hammer 40 free which produces thedetonation at the moment of crashing with the bolt 30.

The action of opening the rifle is repeated resulting in the extractor34 extracting the detonated shell and at the same time resulting in thecartridge being located in the cartridge feeder 20 and fed into therifle. As the hammer 40 and bolt 30 are returned to their initialpositions, the bolt rotates and at the same time pushes the safetytoward the back and a light click is heard, corresponding to thealignment of the vertical markings of the spring 66 and the verticalalignment grooves in the curved section observing that the red alertpoint 75 is visible.

Again the second cartridge is introduced into the chamber via the bolthandle 36; at the same time the cartridge feeder is loaded with anothercartridge. The user may proceed to shoot after releasing the triggersafety 60. In this form, a double-shot rifle is achieved.

If the return stop screw 68 is manually removed, the rifle becomes arepetition rifle, but in this case the safety must be placed manuallyand not automatically.
